She posted a photo on Instagram in an outfit that made her look ready for the carnival. But eagle-eyed fans spotted there was something very wrong with RiRi’s picture.

Strangely, she seems to have two thumb nails on her right hand.

Fans were very quick to comment on it.

One said: “am i the only one seeing two nails coming from her thumb”

“Why does her thumb got two nails,” asked another.

The picture of the 29-year-old in a bejewelled bikini and teal hair even drew a comment from former flame Chris Brown.

He posted the ogling eyes emoji under the picture. His reaction to her Instagram post sent her fans into meltdown with many warning the man who assaulted the pop star back in 2009 to stay away from her.

“Rihanna don’t need this kind of negativity in her life,” one wrote, while another shared, “Please keep your negative energy away from Rihanna @ChrisBrownOfficial.”

And: “Can Riri flourish in peace.”

Last year Chris admitted that he considered killing himself after assaulting his ex-girlfriend.

The flirty comment was soon noticed by eagled-eyed fans, who mostly slammed the 28-year-old Five More Hours singer.

“I was thinking about suicide and everything else,” he said. “I wasn’t sleeping. I wasn’t eating. I just was getting high.”

Rihanna was ready for the annual Crop Over Festival and Kadoonment Parade – a traditional harvest festival in her native Barbados – which she attends every year.

Whether the photo glitch is down to some bad photoshopping we are not sure, but Rihanna still gets our praise for style and class.
